Globally, obesity has skyrocketed since 1980, from 857 million overweight or obese individuals that year to 2.1 billion in 2013, researchers said, after an analysis of trend data from 188 countries.

Of that number, 671 million are obese. Fifty percent of the globe’s obese individuals live in just 10 countries, researchers said: U.S., China, India, Russia, Brazil, Mexico, Egypt, Germany, Pakistan and Indonesia.

In the U.S., more than two thirds of individuals are overweight or obese, according to the U.S. Centers for Disease Control and Prevention. But it might come as a surprise to some that this is not the highest single-nation rate in the world.

According to the most-recent report, obesity among young people is increasing around the world.

"Obesity is an issue affecting people of all ages and incomes, everywhere," said Dr. Christopher Murray, director of IHME and a co-founder of the Global Burden of Disease (GBD) study, in a press release. "In the last three decades, not one country has achieved success in reducing obesity rates, and we expect obesity to rise steadily as incomes rise in low- and middle-income countries in particular, unless urgent steps are taken to address this public health crisis."
